fuel mileage ?

Mart said:
10 mpg is a bit heavy for any old Ford. You'd get that from a 59 Caddy. You probably have an over rich condition in the carb. There are many threads on here re 94 carbs and getting them to run right. There may also be other inaccuracies in your calculations. things like fuel leaks, fuel sloshing from the tank on turns, stuff like that.

My Dad had a factory stock 59 Caddy Coupe Deville in 1960 and it got 17mpg around home and 21 on trips. No joke.:)
 
Members of my dad's generation who started out driving T's said a T (20 HP) could get 20 mpg if driven carefully. Then came the A (40 HP) which also could get 20 mpg. Then the V8 (65-125 HP) which could also achieve 20 mpg. Next Y-blocks (over 200 HP) could do 20 mpg w/three speed and O/D. Then 300+ HP big blocks doing 20 mpg on the highway. Now 500-600 HP cars rated at over 20 mpg hiway. Progress has been made!

I originally thought I have a 16 gal. tank . When it was down to 1/2 after x amount of miles , I figured I went through 8 gal. during those miles . Then I found out I have a 14 gal tank , and instead went through 7 gal . in those same amount of miles . So in this scenario the size of the tank is a factor , as I realized that I went through less fuel than I had originally calculated . I know how to calculate fuel mileage , but got a little messed up here because a: thought I had more fuel for 1/2 a tank and b: my speedo is off a bit . However , I know the distance between my house, and a friends to be 15 mi. , so I base it on that w/ 2 round trips . Hope this all makes sense !
Thanks for your reply - F F

Understand what you are saying and have heard of people attempting to figure mileage this way before. It might be OK for a wild a** guess, but that is about it. It is not going to tell you much. There are too many guesses along the way to be of much value. Even checking it with the mileage and amount it takes to refill is somewhat of a guess, that's why it takes several and/or constant monitoring over a period of time to get any real idea of where you are on MPG.
 
I will check it several times in the coming weeks and see what I come up with as an average . Thanks to all that replied ! - F F
 
My '48 F-1 gets 17 to18+. It has an 276 flathead with 2 carburetors, Offy heads, etc. Has 3.92 rear axle ratio. I don't drive it for gas mileage.
